Method and system for controlling buffer playing streaming media

Abstract

The invention provides a method and system for controlling buffer playing streaming media. The method comprises the following steps: a multimedia information server receives a playing request; the multimedia information server slices and packages a streaming media video into a streaming media data packet; the multimedia information server caches the streaming media data packet in a buffer pool; the streaming media data packet in the buffer pool is transmitted to a streaming media playing terminal, and meanwhile the streaming media data packet is stored in a sent pool; a time threshold of storing the streaming media data packet and a data packet threshold are preset in the sent pool according to a current network speed; whether the difference of a transmission time of the streaming media data packet in the sent pool and the current time exceeds the time threshold is judged; and the number of the streaming media data packets in the sent pool is compared with the data packet threshold. According to the method and system provided by the invention, the multimedia data are sent by controlling an code rate mean, the data exceeding the threshold are cached to effectively avoid frame loss, blockage or instable output and other phenomena of the streaming media in a playing process, and thus the watching effect of users is improved.

Description

technical field [0001] The invention relates to the technical field of streaming media playing, in particular to a control method and system for buffering and playing streaming media. Background technique [0002] With the continuous development of Internet technology, multimedia information such as audio / video is transmitted more and more frequently on the network. At present, there are mainly two schemes of downloading and streaming. The download method requires all the multimedia files to be downloaded before they can be played. Because the multimedia files are usually large and due to the limitation of network bandwidth, it often takes several minutes or even hours to download a multimedia file in the download method, so this processing method has a long delay. Big. [0003] The stream transmission method refers to the continuous and real-time transmission method of audio / video and other multimedia information from the multimedia information server to the client. The c...

Problems solved by technology

[0005] In order to solve the problem of Internet bandwidth constraints and the stability of the network itself in the existing technology, in order to ensure good video playback quality, there will still be frame loss, freeze or output instability during streaming media playback, which will affect users' viewing Experience, if there is a disconnection of the network, it will lead to a reduction in the amount of streaming media cache data. When this situation lasts for a long time, it will lead to the exhaustion of the cache data. The process is stuck, and the user will not be able to watch it at this time. The present invention provides a control method and system for buffering and playing streaming media.
